Nested DO Loops

You can nest do-loops one inside the other. The counter for each loop must have a different name.

do !X to 10

 do !Y

 !Z = !X + !Y

 break if (!Y GT 5)

 enddo

enddo

The inner-most loop goes through all the values of !Y before the outer loop moves on to the second value of !X. Note that the break (or skip) command acts just on the loop containing it - in this case the inner-most loop.
